TIRE-PUMP.

To all whom it mat/concern:

- Be it known that I, HUsroN TAvLoI'i, a

citizen of the United States, and residing tit-Detroit, inthe county of Vayne'zmd State which may be quickly secured in operative position or may bereadily detached from the car altogether. V r

The invention consists in an improved bearing means for the pump shaft whereby the latter'is detachably "supportedin substantial alinement with a driven shaft of the vehicle; also in improved means for preventing rotation of the pump body about the axis of the drivenshaft; also in the details of construction shown, described and claimed.

In the drawings, Figured is a part side view, part vertical section through the front end of a motor vehicle showing the pump clutched to the engine'l shaft but not yet clamped to the guide securing nut. FigQZ is a similar view, the pump being" turned down substantially90 and clampedtoth'e nut. Fig. Sis a view corresponding to Fig. 1, illustrating another embodiment of the invention. Fig. {is aperspective view of the pin whereby thejpump is prevented from rotating. Fig. 5 is a fragmentary view, similar to Fig. .3, showing the pin inserted betweenthe frontcross bar and the mud or dust pan. Fig. 6 is a part vertical section,

part elevation showing a third embodiment. Fig. 7 is a fragmentary bottom plan view corresponding toFig. .6. i

Specification of Letters Patent. Paten ted Feb, 22, :1921 Application filed December 16,1915. seria no. 57,146,

hose (not shown) maybe attached,fis preferably of the well-known diaphragmtype andprojecting therefrom is. a tubular bearing l1 in;-which the pump shaft 12 is-rotatable; The latter projects from v the bearing and has secured theretoby the cr'oss pin 13,

or. otherwise, a tubularflclutch', member 14 slotted to receive the clutch member 7 Inv7O terposed between the pump shaft an dv. the j guide 4 and fitting. closely to the inner' surface of thelat-ter is a bearing 15, t he longitudinal movement of which, relatively to the pump shaft, is limited by the cross pin16. The external dimensions of this bearing' nay be varied toconform to the guides 'on the different cars so that it is only necessary to change the bearing (by removing the ,7 pins 16 and .13. and the clutch member 14) in order to adapt the pump to aparticular, car.

The pump'bodyis provided with alug 18 having a contact face 19 which comes into engagement with the face of the nut .6

or bolt "5, asthe'case maybe, when the pump is swung toward theobserver substantially from the position shown inFig. 1, as

best indicated in Fig. 2." 'Monnted on a pivot 20,.wh' ich projects from the lug in a line at right angles to thefface'l9, is a clamp ing lever 21, the end 22tof whichis adapted to engage the nutorbolt on the side opposite the face, a spring .wa'sher '23 being interposed "between the leverand the head of the pivot whereby the lever is allowedto accommodate itself to-variations in size and fad justment of the nut orbolt and wherebyit is held in resilient clamping relation thereto. It will be understood that the engine shaft normally turns in the direction indicated by the arrow, in Fig. 1, which causes the face 19 to bear directly on the nut orbolt; the clamping lever prevents backlash or In the embodiment, ofthe invention illustrated in Figs. 3 and 4, the guide or sleeve 2 1, which corresponds to the guidel t, extends rearwardly through the perforation in the cross bar, being secured in place pressing or otherwise. Theradiator' is shown at 25, its bottom 26 being, as usual, spaced slightly from the upper flange 28 of thecross bar. body and projecting therefrom in a line parallel to the pump shaft is a pin 29 adapted to be received between the bottom 26 and flange 28, whereby rotation of the pump body about the axis of the engine shaft is prevented. Since thespace between the bottom and flange is both small and variable, it is preferred to flatten the end 30 of the pin 29 and to provide a lock nut 31, thus allowing the pin to be turned in such man pin is inserted between the lower flange 32 of the cross bar and the upper face of the mud or dust pan 83. y

In either of the two constructions last described, it is only necessary to insert the 1" pump shaft through the guide until the clutch members are engaged,after which the pump body and engine shaft may be rotated until the pin 29 comes lnto alinement with the slot or opening, whereupon the pump is thrust rearwardly until the parts are fully engaged.

Referring now to Figs. 6 and 7, the means whereby the pump body is prevented from rotating consists in a clip 34, preferably resilient and pivoted by the screw 35 to a lug 35 on the body. This clip includes the hooked upper end 36 that engages over the upper edge or face of the cross bar 33 and the offset, preferably hook-shaped lower end 89 that contacts with the lower face of the cross bar andprevents back lash or reverse motion of the pump. By grasping the end 39 and pulling forwardly, it may beeasily disengaged from the cross bar, after which the pump may be turned backwardly a slight distance and the pump drawn for wardly and detached from theengine shaft. It will be observed that the clip, when engaged, prevents both rotative and longitudinal movements of the pump body in respect to the axis of the engine shaft, and that it may be turned about the screw 35 to accommodate itself to the depth of the cross bar of the particular car, after which the screw may be set up to clamp the clip in position.

It is clear that the details of construction may be varied without departing from the spirit of my invention. I do not, therefore, wish to be limited otherwise than as indicated by the subjoined claims.
